An incredible new study suggests that low-intensity ultrasound can be used to target very specific brain regions and alter an animal's decision-making processes. The technique, demonstrated in macaques monkeys, prompts actual behavioral changes using non-invasive ultrasound waves...

We've been hearing a lot lately about how living cells can be combined with polymer gels, the mix then being 3D-printed to create biological tissue for use in transplants or experimentation. Such material could soon be getting even more like the real thing, thanks to new ultrasound tech... Continue Reading Cell-herding ultrasound developed for better bioprinting Category: Science Tags:
A promising new study is documenting the long-term effects of a novel surgical procedure using ultrasound to reduce blood pressure in patients with hypertension. The one-off procedure, called renal denervation, is hoped to offer patients an alternative option to taking hypertension drugs...

Ultrasound technology has been in wide use for decades, helping submarines navigate and letting doctors non-invasively peer inside patients, but it might be about to get a whole lot more powerful. Researchers have developed an "ultra" ultrasound sensor that is so sensitive it can hear air molecules moving around or the vibrations of individual cells. .. Continue Reading New "ultra" ultraso
Although wind turbines may be a valuable source of eco-friendly energy, they do have at least one drawback – bats are frequently killed by their spinning blades. A promising new system is designed to help keep that from happening, however, by producing an ultrasonic acoustic field...

Earlier this year, we heard how scientists from the University of California San Diego had developed a flexible ultrasound patch that allows users to see the inner structure of irregular-shaped objects. Well, now they've made one that measures a patient's blood pressure from deep within the body... Continue Reading Ultrasound patch goes deep to better-monitor blood pressure Category: Medi
Ultrasound equipment doesn't come easy, often taking the shape of large, clunky contraptions that cost tens or hundreds of thousands of dollars. In a bid to make these invaluable medical machines more accessible, engineers in Canada have developed a new type of ultrasound device the size of a Band-Aid, with a similarly scaled down price tag to match. .. Continue Reading Band-Aid-sized ultr
Scientists are reporting success in using ultrasound to treat cognitive dysfunction in mice with simulated vascular dementia and Alzheimer's disease, which are the two most common forms of dementia. Applied to the whole brain, the ultrasound improved both the formation of blood vessels and the regeneration of nerve cells... Continue Reading Ultrasound used to treat dementia in mice Catego
A promising new cancer drug delivery system has successfully passed early human safety trials. The treatment delivers cancer drugs in heat-activated capsules to tumors in the liver and then uses a focused ultrasound beam to remotely trigger the targeted release of their drug payload... Continue Reading Ultrasound remotely bursts heat-sensitive capsules, delivering drugs directly to tumors
Finding ways to activate or deactivate specific neurons in the brain could be the path to treating disorders like Parkinson's or epilepsy, but usually that requires surgery. Now, Caltech researchers have developed a three-part technique that's far less invasive, combining ultrasound waves, gene therapy and drugs that has been able to affect memory formation in mice...
